To 1/ irliom it may concern:

lie it known that l, RUDENZ S. DOUTIIAT, cltlZt'ii of the United States,residing at Huntington. in the county of Cabell and t tate oi WestVirginia, have invented certain new and use'tul Improvements inTypelt'riting ltliltlllllvti; andIdoherehy declare lllt following to hea full, clear, and exact description of the invention, such as willenaid others skilled in the art to which it up pertains to make and usethe same.

.dv invention relates to. typewriting machines and consists of certainnew and usetnl in-iprrwements in attachments for that class oi machines.wherein a single key hoard is used'and a s tting mechanism is provided:lor changing the relative position of the platen or the type basket, inorder to permit a capital letter or other selected charactor to lapositioned for printing, and wherein a depressihle space bar or key islocated in i'ront' ot tholcey hoard for spacing the writing.

.dv inventi n relates more particularly to that class of machineswherein the platen or t'vpc asket is shifted in a suhstantiallyhoriontal direction to etl'cct the printingof a capital letter or otherselected character.

The main object of my invention is to increasc the ease and speed ofoperating niachines oi this class. by providing devices by which theshift mechanism may be operated by means of a depressihle shift har,located dirc tlv in front of the key board. and ex tendlnlj from aboutthe center of the Front to the lel t hand margin oi said key hoard andon a line with the space bar. I acconn plish this object in my preferredform oi" device h v dividing the space bar. ordinarilv provided for suchmachines. at ahout its central portion. and using the left subdivisionof said space har. when properly connected to coacting parts. 'l'oroperating the shift; mechanism, and the right hand subdivision i oi saidspace bar, for the spacing required in operating 1 spacing beingaccomplished by the downward pressure of the left subdivision to effectthe shitting from lower to upper case 3 for capitals or other selectedcharm-tors and by the downward pressure or movement of the right. handsubdivision for necessary spacing. 'lhisarrangement is especiallydcsirahlc in order that; the operation of shifting. which at present isattained by the use he machine. the shifting and l ,upon 'the space bar13. the spacing will he l l l i l l l i by means of the bent rod c whichis secured key aard, and avoiding the present. objec- G0 ti of theordinary machine, wherein it is necessary to vary the fingering of thekey board in the operation of the shifting mechanism. thus retarding andhindering the operation of the machine.

My invention has for its further object, the production and arrangementof parts to accomplish the desired results, which may be attached tomachines already in use, in a simple and inexpensive manner.

In order that my invention may be clearly understood, I have illustratedit in the accompanying drawings, and described the same with referencethereto, in the following specification and claims.

In the drawings. Figure 1 is a top plan view of a portion of a typewriting machine with my invention attached thereto. Fig. 2 is a similarview oi a moditic tion of the same. Fig, 3 is a modification of Fig. 1and shows the connecting rods made integral.

Similar letters of reference indicate identical parts throughout.

The space bar B is secured at one end to theshifting rod 7 of the machine, and at its other end to the bent rod Bwhich is secured to the shift rod 7) corresponding to the rod 7). aportion of said rod 7) being removed. The connection hetwccn the rod Band the rod 71 may be effected in any desired manner. hilt in"the l'ormshown, I provide the rod l1 with an extension c having projectingflanges which may he hcnt around the rod 7/ to form a secure joint. asclearly shown in Fig. l oi the drawings. l t is obvious that by pressingdownward etl'ected in the usual manner. The shift. har l) is connectedto the shifting mechanism to the shift bar I] in a manner similar tothat. described in regard to the spacing mechanism. The opposite end otthe space har -l has secured to it a short connecting rod (5 which issecurely i'astei'icd to the shifthar this reversal of the arrangement ofthe saiol I connecting'rocls-does not-affect the appli-i (Zcorresponding to the bar Ihe mocleof operating the shift'bar D is thesame as that relating to the space bar B,"
